Millions of people in Mexico City suffer from a serious water shortage and fear among hardships the arrival of 'day zero' These are the strategies that many people use to survive water rationing due to historical circumstances now aggravated by the climate emergency. Persistent drought and years of low rainfall have brought Mexico City's already limited tap water supply system to the brink of collapse.

More than 21 million people have been suffering from rationing for weeks with reservoirs at historically low levels. The region's complicated relationship with water is as old as the city itself, which sits on the bed of a high-altitude lake.
